Technology

Of course the word technology tends to refer to all the very clever gadgets that have come into the world and now threaten to fill our streets with self driving cars and our skies with drones.  But some of my favorite technology is the most basic, like really good knives that retain their edge.  I have two knives I keep in sheaths in a drawer.  I have another knife that looks very similar that I hang with my other kitchen knives on a magnetic bar near my sink.  The sheathed knives are far superior to the look-alike.  They rarely if ever need to be sharpened.  The other knife seems to dull very soon after I run it through the sharpener. 
I am grateful for simple but excellent technology.
